Description

Technical Field

[0001] The utility model relates to the technical field of AGV vehicles, in particular to a stable forklift type AGV vehicle. Background Technique

[0002] In current transportation and logistics operations, the handling of goods is generally completed by forklifts. With the development of automated goods handling, forklift type AGV vehicles are gradually widely used in the handling industry. AGV vehicles play a prominent role especially in intelligent logistics. In practice, there are often cases of handling materials with regular pallet length and width dimensions but relatively high height. Especially in warehouses, there is often a large amount of logistics handling. However, in order to increase the storage capacity of the warehouse, the logistics handling aisles need to be compressed as much as possible. In such a situation, it is easy to occur that the handling process is not stable and reliable, and there is a possibility that the handled goods will fall over. After the AGV vehicle runs for a long time, when handling goods, the positions of the two forklift arms may not be able to accurately align with the center of the pallet for placing goods, resulting in a relatively large offset of the positions of the two forklift arms relative to the center of the pallet for placing goods. If the forklift type AGV vehicle picks up goods when the offset between the position of the forklift arm and the center of the pallet is large, it will cause the goods on the pallet to shake during handling, and even cause the goods on the pallet to collapse and be damaged. Therefore, it is necessary to design new technologies to improve the stability during the handling of a large amount of goods. Content of the Utility Model

[0020] The stabilizing mechanism includes an electric telescopic plate 8, a storage battery 9 and a storage box 10. There are two storage boxes 10, which are respectively arranged outside the two fork arms and fixedly connected thereto. The electric telescopic plate 8 is arranged inside the storage box 10, and the electric telescopic plate 8 is electrically connected to the output end of the storage battery 9. The storage battery 9 is arranged on one side of the fork arm rear plate and fixedly connected. A certain number of baffles are arranged inside the electric telescopic plate 8, and each baffle is slidably connected. The electric telescopic plate 8 limits the goods on the fork arm 701 to prevent the possibility of the transported goods from tipping over.

[0021] The steering mechanism includes a chassis 15, a certain number of moving wheels 11, a driving motor 12 and a connecting shaft 121. There are four driving motors 12. One end of each driving motor 12 is meshed and connected to a moving wheel 11, and the other end of the driving motor 12 is fixedly connected to the connecting shaft 121. The connecting shafts 121 provided at the other ends of the four driving motors 12 are fixedly connected to each other, and the connecting shaft 121 is fixedly connected to the top of the chassis 15. The trolley can achieve in-situ steering, in-situ turning around, reduce the turning radius of the trolley, and increase the storage space in the warehouse.

[0022] In some embodiments, infrared distance sensors 13 are provided inside the two fork arms 701. The infrared distance sensors 13 are electrically connected to the control panel 3. The goods to be carried are measured by the infrared distance sensors 13 to adjust the distance between the fork arms 701.

[0023] In some embodiments, the input end of the electric telescopic plate 8 and the output end of the pressure sensor 5 are electrically connected to the control panel 3. A laser generator 14 is provided outside the innermost baffle of one end of the electric telescopic plate 8, and a laser receiver 141 is provided outside the innermost baffle of the other end of the electric telescopic plate 8. The electric telescopic plate 8 can be controlled to start and stop automatically through the laser generator 14 and the laser receiver 141.

[0024] In some embodiments, multiple layers of baffles 801 are provided inside the electric telescopic plate 8. When the electric telescopic plate 8 is started, its innermost baffle 801 rises first and then rises successively in sections.

[0025] Embodiment 1

[0026] Combined with Figures 1-4 As shown, the working principle and usage process of the present utility model: When the forklift-type AGV trolley carries goods, the infrared distance sensors 13 provided inside the fork arms 701 detect the width of the goods, and the distance between the fork arms 701 is automatically adjusted through the control panel 3 to ensure that the goods are exactly in the middle inside the fork arms 701. Storage boxes 10 are installed outside the two fork arms 701. An electric telescopic plate 8 is provided inside the storage box 10. A storage battery 9 is installed outside the rear plates 7 of the two fork arms. The storage battery 9 is electrically connected to the electric telescopic plate 8. When the pressure sensor 5 on the fork arms 701 senses the weight, the electric telescopic plate 8 automatically rises. First, the innermost baffle 801 rises, and then it rises successively in sections. A laser generator 14 is provided on the innermost baffle 801 of one side of the electric telescopic plate 8, and a laser receiver 141 is provided on the innermost baffle 801 of the other side of the electric telescopic plate 8. When the laser emitted by the laser generator 14 is received by the laser receiver 141, the electric telescopic plate 8 stops rising. At this time, the rising height of the electric telescopic plate 8 is slightly higher than the height of the goods, which plays a role in limiting the goods and preventing the risk of the goods collapsing during transportation and reducing the occurrence of safety accidents.

[0027] Embodiment 2

[0028] Combined withFigures 1-4 As shown, when the pressure sensors 5 provided on the two fork arms 701 sense the weight of the goods, a situation of unstable center of gravity may occur. At this time, the top of the hydraulic rod 2 fixedly connected by the flange plate 4 on the rear plate 7 of the fork arm presses against the support plate 1 in the working box, causing the rear plate 7 of the fork arm to rotate actively around the hinge position with the connecting plate 6. The rear plate 7 of the fork arm drives the front end of the fork arm 701 to move upward, adjusting the center of gravity of the goods to make it balanced on the fork arm 701 and preventing the forklift from tipping over due to the deviation of the center of gravity.

[0029] Embodiment III

[0030] Combined with Figures 1-4 As shown, there are four drive motors 12 inside the chassis 15, and each drive motor 12 controls a moving wheel 11 independently. When the in-field turning angle is insufficient, the drive motor 12 can be used to make the moving wheels 11 on one side of the chassis 15 rotate clockwise and the moving wheels 11 on the other side of the chassis 15 rotate counterclockwise, realizing in-situ turning and U-turning and saving the storage space for goods.

[0031] Embodiment IV

[0032] Combined with Figures 1-4 As shown, the electric telescopic plates 8 provided on both sides of the fork arm 701 are fixedly connected to the fork arm 701. When the center of gravity of the goods deviates, the fork arm 701 adjusts the inclination angle of the fork arm 701 through the hydraulic rod 2 provided on the rear plate 7 of the fork arm, and the electric telescopic plates 8 on both sides tilt synchronously with the fork arm 701 to ensure that the fork arm 701 is perpendicular to the electric telescopic plates 8, preventing gaps from appearing between the fork arm 701 and the electric telescopic plates 8 when the inclination angle of the fork arm 701 is too large and causing the goods to fall.
